How to generate a new GUID?

guid, php

Solution

You can try the following:

function GUID()
{
    if (function_exists('com_create_guid') === true)
    {
        return trim(com_create_guid(), '{}');
    }

    return sprintf('%04X%04X-%04X-%04X-%04X-%04X%04X%04X', mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(16384, 20479), mt_rand(32768, 49151), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535));
}

Problem

I'm working on a web service which requires a new `GUID()` passed as a reference to a method within the service. I am not familiar with `C#` or the `GUID() object`, but require something similar for `PHP` (so create a new object which from my understanding returns an `empty/blank GUID`). Any ideas?
